Did you made the graphics?

Why "move_forward" instead of a shorted world like "forward"? (What does the turtle in Logo use?)

move_forward is more descriptive as a method name.

- the action name of move is significant.

the additional typing for a precisely descriptive name is generally worth it for readable code.

fortunately, autocompletion is available in the code editor!

Nice! Learning Python by playing a game should be very interesting for the kids.

As for me, just what is needed for learning programming language in an easy and playful form.
